Real-Time Object Detection for Unmanned Vehicles in Bangladesh: Dataset,
Implementation and Evaluation
Abstract
Intelligent identification of road vehicles in a densely populated
country like Bangladesh is challenging due to irregular traffic
patterns, highly diverse vehicle types, and a cluttered environment.
This study proposes a system that utilizes computer vision technology to
identify road vehicles with greater speed and accuracy. Firstly, dataset
was collected and organized in Roboflow to identify 21 classes of
Bangladeshi native vehicle images, along with two additional classes for
people and animals. Subsequently, YOLOv5 model underwent training on the
dataset. This process produced bounding boxes, which were then refined
using NMS technique. The loss function CIoU is employed to obtain the
accurate regression bounding box of the vehicles. MS CO-CO dataset
weights are included in the YOLOv5 deep learning network for transfer
learning. Finally, Python TensorBoard was used to evaluate and visualize
the model’s performance. The model was developed and validated on Google
Colab platform. A set of experimental evaluations demonstrate that the
proposed method is effective and efficient in recognizing Bangladeshi
Vehicles. In all test road scenarios, the proposed computer vision
system for road vehicle identification achieved 95.8% accuracy and
0.3ms processing time for 200 epochs. This research could lead to
intelligent transportation systems and driverless vehicles in
Bangladesh.
